Does anyone have this problem? Thought it might have been from me not getting any sleep from the night before that it hurt yesterday but after a full hour's rest tonight it still is an issue. I have turned down brightness and text size. Some of the non-optimized iOS 8 apps are an extremely over sized though. This is not a complaint thread, it is obvious that I may have to swap for the 6.. which I don't have a problem doing if I need to. I am just trying to see if others have had this problem and what they have done to deal with it or could it be my eyes trying to adjust to this huge screen. It's surprising to me that this is even an issue because I am in my 20s with perfect vision. Thanks!
